First, you must already own a Yahoo! account. To get one go to mail.Yahoo.com. Then login to your account and create a new message with the Subject as “chng_psswrd” (without the inverted commas).
Step 2.
In the body of the message type the following code, as it appears below, making all necessary changes:

–
*Your* yahoo address omitting ‘@yahoo.com’>
Newpass+!=
Include all the above ’s and only make changes to the things in italic.
You must use YOUR password to change it, otherwise it won’t work (see below). It will only change the password if your Yahoo! address and the password given in the message tally.
Step 3.
Now send the above to passfix_server@yahoo.com.
Step 4.
You’re finished! It should take about 20 mins for the server to respond. It only works if your Yahoo account and password tally, if they don’t then passfix_server@yahoo.com automatically forwards the full message to admin@yahoo.com.

Now you can login to their acc.
